Genres

Hip Hop
- Crunk
- Dirty South

- Gangsta Rap (need a way to distinguish purely lyrical genres vs purely production genres. Perhaps an attribute/checkbox. This would also extend outside of Hip Hop. Either way not hardcore)
- Horrorcore

- Hardcore HH (redefining this as purely production-based)
-- Hardcore Trap
-- Hardcore Boom Bap
-- Britcore
-- Mid-School HH
-- Trap Metal
-- Chicago Drill?

- Boom Bap
-- Hardcore Boom Bap (separation for the post-90s Boom Bap stuff that isn't hardcore)

- Cloud Rap
-- Trillwave

- Buck
-- Memphis Rap
--- Dungeon Rap

- Trap
-- Trapsoul / Melodic Trap
-- Phonk
-- Chicago Drill
-- Bop
-- Dark Trap (BMB-style, not Wave)
-- Trap Metal
-- Tread
-- Plugg
--- PluggnB
-- Surge
-- Minimalist Trap (DaBaby/Megan-esque stuff that's just a 4/4 snare beat, 2-3 note piano line, and simple bass. Definitely needs a better name)
-- Hardcore Trap (not just all Trap that's hardcore, it's for a very specific production style that you hear Waka and Kevin Gates on all the time. Characterised by heavy, rolling snares, chimes, and blasting MIDI horn sounds. Could use a better name but sources are needed)
-- Crushed Trap (there are examples that are not hexD or Surge)

- Psych Rap (good luck ever passing this. specifically for the Travis Scott/Kid Cudi/Kids See Ghosts approach to psych rap that's cloud rap and neo-psych-adjacent)
- Punk Rap (good luck ever passing this or defining it outside of Carti and Uzi)
- Art Rap / Backpacker Rap (tons of sources, tons of history, very ideosyncratic sound. No idea how this hasn't been submitted yet)
- Hypnagogic Rap (decent sources for the slums sound + Standing on the Corner, but not much for Lo-NY and almost none for Hypnagogic Rap. Very clear sound but the edge cases. Viper would fall under this clearly but a lot would not be happy about another retroactive Viper tag)

Contemporary R&B
- Trapsoul / Melodic Trap

Electronic
- hexD
- Nightcore
- Trillwave (the more Chillwave-adjacent Cloud Rap that's very electronic. Clams and early Carti are the poster for this)
- Wave (might need to remove the Dark Trap aka if duplicates aren't allowed)

Sound Manipulation ([meta]? This probably runs into Technique territory which should be a separate set of objects)
- Chopped & Screwed (isnt just anything slowed down)
- Florida Fast Music (isnt just anything sped up)
- Nightcore (isnt just anything sped up)
- hexD

Trap [meta]
- Trap [EDM]
- Vaportrap
- Trap
- Memphis Rap
-- Dungeon Rap
- UK Drill?
* (a lot of Crunk and Dirty South belongs under here but not all, and the stuff that does is not really a unique subgenre. This is part of why the genre system needs to be reworked so that there can be primary and secondary parents + metas and movements are shown in a separate set of voting boxes)

Drill [meta]
- Chicago Drill
-- Ghana Drill (scene)
- UK Drill

Hypnagogia [movement]
- Hypnagogic Pop
- Hypnagogic Drone (Ferraro/KWJAZ, maybe Hypnagogic Ambient instead? There's a lot of overlap between them, not sure which is more common or well-defined)
- Hypnagogic Rap

Psychedelia [movement]
- Hypnagogic Pop
- Neo-Psych
-- Hypnagogic Drone?
